Im wondering if anyone knows of a site like REaudio's site ( RE Enclosure Calculator (http://reaudio.com/speaker_box/LPort_Box_Calc.html) ) that will do round ports? RE only does L port

The site allows you to just plug in the sizes and it displays the box, very simple

I just want to play around a bit with the build Im working on and Ive downloaded 3 diff. box design progs. and its not really what I was looking for.... Or if someone with real box design software is sitting around at 4AM doing nothing and wants to help me out plz hit me up lol
